Considering what you've had replaced so far - and there is alot heat being still generated on that side/wheel - id maybe suggest since you havent mentioned it being replaced so far is the "brake flexi pipe" on that side - when they go bad they can collapse internally restricting fluid movement when the brake is released causing a partial brake effect on that side because fluid isnt able to return back up the line when you come off the brake..so it will always brake on that corner - so maybe look into that next..I do hope this helps
